About prefects and Head Boys/Girls?

According to link Head Boys and Girls are chosen from all the seventh years. Perhaps it's easier to be chosen if 당신 were a Prefect before, 또는 maybe it was just a coincidence that all the Head Boys and Girls we know about were Prefects?

I'm pretty sure Remus was still a prefect. You're right, usually it's 2 prefects that become head girl and head boy. So I'm just guessing here, but I think James wasn't mature enough to be a prefect in their 5th year, and Remus obviously was. 의해 their 7th year, he was, and James was probably 더 많이 of a leader than Remus. Sorry, I'm just guessing here, someone else might give 당신 a better answer.

Maybe this is just me not having read the 책 properly (shame on me if that's the case!) but where does it say that James becomes Head Boy? For the life of me I can't recall having ever read that.
